In using property 6 make sure that the logarithm that you subtract is the
one that contains the denominator as its argument. Also, note that that I’ll be converting the
root to exponents in the first step since we’ll need that done for a later
step.

You can use Property 7 on the second term because the WHOLE term was raised
to the 3, but in the first logarithm, only the individual terms were squared
and not the term as a whole so the 2’s must stay where they are!
